  Subject: From box2d to bbox


  Hi all,

      I´m trying to create geoserver images from postgis and need a bbox parameter to pass to geoserver.So, i need the minx,miny,maxx,maxy from the box2d of each feature. I can make the boxes but i don´t  find any functions to access to perimeter´s points. I see few point functions but only for linestrings. I supose i have to transform polygons to perimeter polylines but i don´t know how. Any idea?
      Perhaps there is a better aproach, so any suggestion will be wellcomed :)
